k bought it downloaded it installed it now when i start it asks me for my key i enter it than hit the send button than not 2 secs later it stops responding and crashes all i get for an error message is the windows message saying that Dof updater has stopped responding

does any one have a clue how to fix this i have tried every thing and still the same exception occurs the only thing that i cant change is the dam updater so what is going on i have everything up to date my vid drivers, windowsupdates, Microsoftframe, and just about every other driver on my rigg but still the same problem
